The life span of a electric battery bloc can vary dramatically specially when found in a UPS System , the maker will always state the expected lifestyle of a electric battery bloc on the proviso that it includes a pure dc float voltage applied to it and that the ambient heat range is fixed to 20 ° C. If these parameters are honored, one can be prepared to achieve the 5 years life from a 3 – 5 year design life battery or the 10 years of a 7 – 10 year design life electric battery bloc, omitting manufacturing failures.
Unfortunately we usually do not live in an ideal world and consequently there are restrictions applied to the battery bloc, one is the ambient temp, although several rack-attached UPS systems may luxuriate in ambient temperature ranges of 20 ° C or less because of the needs of the IT equipment, due to the nature of the design of the UPS there is normally insufficient space to accomplish a significant airflow round the battery blocs and consequently they’ll fail the UPS program battery check after a mere 2 – three years.
In this situation certain requirements of Uninterruptible power products and their installation mean that UPS maintenance is definitely unlikely to detect the failing of the battery pack, often because of the fact that after an extremely short period of time the UPS program is concealed in a mass of communication cables. The most positive approach under these circumstances is to rigorously apply a two-year replacement battery pack programme to guarantee the integrity of the back-up UPS program. This also pertains to Generators. Yes, also diesel generators need batteries to provide the current to start out.
Smooth or failed batteries render the generator useless. Contact outs to such complications are chargeable and yet can be prevented by a normal maintenance regime.
In bigger UPS systems the problems arising tend to be because of location; no-one desires the local radiated noise of Uninterruptible power items to impinge on the operating environment and, because of this the uninterruptible power will be positioned in a basement maybe, where the ambient temperature isn’t well suited for batteries and perhaps the word,” Out of sight has gone out of mind,” is true. In the case of battery life, ignorance isn’t bliss. Batteries will fail the issue is certainly whether you are prepared or just waiting for it to happen,
Due to the positioning the ambient temperature can often exceed 25 – 30 ° C which potentially could decrease the expected existence of the battery. For, prolonged make use of at 30 ° of VRLA (valve regulated lead acid) batteries the expected life can reduce by 50%, if the ambient heat is raised to 40 ° C the life of the battery will fall by another 50%. As a result at an ambient heat range of 40 ° C the anticipated operating life of a 7 – 10 year life battery pack has fallen to 1 1.75 – 2.5 years!
In this instance even emergency power supply manufacturer will not save the battery pack, all it could do is certainly to report on the rapid deterioration of the battery bloc.
Fortunately these extremes included in these scenarios aren’t too common however they highlight the need to record the operating conditions by regular UPS maintenance and to ensure that there can be an emergency 24/7 callout cover set up in case of the unexpected taking place. Be prepared!
